I have eighteen years of electronics experience, the last seven years being directly involved in EMI testing. I am qualified to perform EMC testing to the methods described in this test report. The measurements taken within this report are accurate within my ability to perform the tests and within the tolerance of the measuring instrumentation. By:Steven Koster EMC Laboratory Manager Date: 5/11/98 Hughes Network Systems DirecPC Enterprise Relay WLL Project # 4442X 1 FCC CERTIFICATION REPORT for Hughes Network Systems FCC ID: K3Y30025140-40 1.0Introduction This report has been prepared on behalf of Hughes Network Systems to support the attached Application for Equipment Authorization. The test and application are submitted for an approval under the following FCC requirements: 1. Class B Digital Device under Part 15 of the FCC Rules and Regulations. 2. TV Interface Device under Part 15 of the FCC Rules and Regulations. 3. Radio Receiver (Superheterodyne) under Part 15 of the FCC Rules and Regulations. The equipment under test was the Hughes Network Systems DirecPC Enterprise Relay. All measurements herein were performed according to the 1992 version of ANSI C63.4. The measurement equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and field Strength Instrumentation. Calibration checks are made periodically to verify proper performance of the measuring instrumentation. All measurements are performed at Washington Laboratories, Ltd test center in Gaithersburg, MD. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories, Ltd. has been approved by the FCC and NIST NVLAP (NVLAP Lab Code: 200066-0) as an independent test laboratory. All results report herein relate only to the item tested. This report shall not be used to claim product endorsement by NVLAP or any agency of the US Government. 1.1Summary The Hughes Network Systems DirecPC Enterprise Relay complies with the following FCC requirements: 1. Class B Digital Device under Part 15 of the FCC Rules and Regulations. 2. TV Interface Device under Part 15 of the FCC Rules and Regulations. 3. Radio Receiver (Superheterodyne) under Part 15 of the FCC Rules and Regulations. 2.0Description of Equipment Under Test (EUT) The DirecPC Enterprise Relay is part of an Integrated Satellite Business Network (ISBN) which is a private, two- way transmission system for data traffic. All ISBN traffic is carried between a large master station, called the hub, and small, remote Personal Earth Stations (PES’s). The two-way data transmissions are relayed between the hub and the PES via a geosynchronous communications satellite located over the equator. The ISBN can also distribute one- way television video and audio from the hub to remote television receivers at the remote PES. Hughes Network Systems DirecPC Enterprise Relay WLL Project # 4442X 2 Advanced network control processing at the hub supports and controls the operation of the PES equipment. Under normal conditions, manual operation of the PES is not required. There are two configurations for the DirecPC Enterprise Edition Integrated Relay. The first configuration which is designed for commercial use, consists of a PES 5000 (FCC Class A device) coupled with the DirecPC Enterprise Edi…
